From 43edba6b670bc4f5426e77873b400fe91f8d3c75 Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Wed, 20 Mar 2024 04:57:36 -0400 Subject: [PATCH] regulator: rtmv20: convert to use maple tree register cache The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache.
